為讓本發明的上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the invention will be apparent from the following description.

圖1為依據本發明一實施例的監控資料的原始畫面儲存系統的系統示意圖。請參照圖1，在本實施例中，原始畫面儲存系統100包括監視感測器110、事件標記電路120、資料儲存電路130及畫面處理電路140。其中，監視感測器110例如是攝影（camera）或類似元件，資料儲存電路130例如是資料儲存裝置（例如硬碟系統），畫面處理電路140例如是影像處理裝置（例如影像卡）。並且，監視感測器110用以監控特定區域（如走道、出入口）以提供多個原始畫面OF。1 is a system diagram of an original picture storage system for monitoring data according to an embodiment of the invention. Referring to FIG. 1 , in the embodiment, the original picture storage system 100 includes a monitor sensor 110 , an event mark circuit 120 , a data storage circuit 130 , and a picture processing circuit 140 . The monitoring sensor 110 is, for example, a camera or the like, the data storage circuit 130 is, for example, a data storage device (for example, a hard disk system), and the image processing circuit 140 is, for example, an image processing device (for example, an image card). And, the monitor sensor 110 is used to monitor a specific area (such as a walkway, an entrance and exit) to provide a plurality of original pictures OF.

事件標記電路120的輸入端耦接監視感測器110，用以判別監視感測器110所提供的原始畫面OF分別對應的事件強度，並將事件強度分別標記於原始畫面OF上，而提供已標記的原始畫面OFa，其中原始畫面OF的事件強度與影像內容有關但與時間無關。舉例來說，事件標記電路120可判斷原始畫面OF是否發生事件，並且判斷發生事件的原始畫面OF是否為關鍵畫面或必要關鍵畫面，接著依據判斷結果對原始畫面OF進行標記。由於原始畫面OF的標記代表原始畫面OF與特定事件的關聯程度，因此上述標記方式可視為將事件強度分別標記於原始畫面OF上。此外，除了透過影像辨識來進行原始畫面OF標記，也可透過人工審視的方式對原始畫面OF進行標記，本發明實施例不以此為限。The input end of the event tag circuit 120 is coupled to the monitoring sensor 110 for discriminating the event intensity corresponding to the original picture OF provided by the monitoring sensor 110, and marking the event intensity on the original picture OF, respectively. The original picture OFa of the mark, where the event intensity of the original picture OF is related to the image content but is not related to time. For example, the event tag circuit 120 may determine whether an event occurs in the original picture OF, and determine whether the original picture OF of the event is a key picture or a necessary key picture, and then mark the original picture OF according to the determination result. Since the mark of the original picture OF represents the degree of association of the original picture OF with a specific event, the above-mentioned mark mode can be regarded as marking the event intensity on the original picture OF, respectively. In addition, the original image OF is marked by a manual review, and the present invention is not limited thereto.

資料儲存電路130耦接事件標記電路120的輸出端，用以完整儲存事件標記單元120所標記的這些原始畫面。畫面處理電路140耦接資料儲存電路130，用以依據原始畫面OFa的事件強度檢查於資料儲存電路120中的原始畫面OFa，並且在不同的時間區間決定要保留的原始畫面OFa，其中越後面的時間區間所保留的原始畫面OFa越少。The data storage circuit 130 is coupled to the output of the event tag circuit 120 for completely storing the original pictures marked by the event tag unit 120. The picture processing circuit 140 is coupled to the data storage circuit 130 for checking the original picture OFa in the data storage circuit 120 according to the event intensity of the original picture OFa, and determining the original picture OFa to be retained in different time intervals, wherein the later The original image OFa retained by the time interval is less.

圖2為依據本發明一實施例的監控資料的原始畫面儲存方式的時序示意圖。請參照圖1及圖2，在本實施例中，是將原始畫面OFa的存續時間分為五個時間區段，亦即時間區段TP0~TP4，其中時間區段TP0位於時間點T0與T1之間，時間區段TP1位於時間點T1與T2之間，時間區段TP2位於時間點T2與T3之間，時間區段TP3位於時間點T3與T4之間，時間區段TP4位於時間點T4之後，並且依據時間由早至晚排列為時間點T0~T4。FIG. 2 is a timing diagram of an original picture storage manner of monitoring data according to an embodiment of the invention. Referring to FIG. 1 and FIG. 2, in the embodiment, the duration of the original picture OFa is divided into five time segments, that is, time segments TP0 TP TP4, wherein the time segment TP0 is located at time points T0 and T1. Between the time points T1 and T2, the time zone TP2 is located between the time points T2 and T3, the time zone TP3 is located between the time points T3 and T4, and the time zone TP4 is located at the time point T4. Thereafter, and according to the time, the time points T0 to T4 are arranged from morning to night.

對於存續時間落於時間區間TP0內的原始畫面OFa，畫面處理電路140不會進行處理（亦即不會刪除任何原始畫面OFa），因此時間區間TP0內的原始畫面OFa仍會被完整保留。舉例來說，時間區間TP0內的原始畫面OFa包括發生事件的畫面（例如標記EP 、EK 及EN 的畫面）及未發生事件的畫面（例如未標記的畫面），並且在時間區間TP0內，發生事件的畫面及未發生事件的畫面都會保留。For the original picture OFa whose duration falls within the time interval TP0, the picture processing circuit 140 does not process (ie, does not delete any original picture OFa), so the original picture OFa in the time interval TP0 is still completely retained. For example, the original picture OFa in the time interval TP0 includes a picture in which an event occurs (for example, a picture marked E P , E K , and E N ) and a picture in which an event does not occur (eg, an unmarked picture), and in the time interval TP0 Inside, the screen in which the event occurred and the screen in which the event did not occur are retained.

對於原始畫面OFa的存續時間落於時間區間TP1（對應第一時間區間）的第一原始畫面OF1（亦即標記EP 、EK 及EN 的畫面及未標記的畫面），保留在這些第一原始畫面OF1中發生事件的第一原始畫面OF1（例如標記EP 、EK 及EN 的畫面），並且刪除未保留的其他原始畫面OF1（例如未標記事件的畫面）。其中，上述事件例如是物體移動、有火焰或煙霧。The first original picture OF1 (that is, the pictures marked with E P , E K and E N and the unmarked picture) whose duration of the original picture OFa falls within the time interval TP1 (corresponding to the first time interval) remains in these The first original picture OF1 of the event (for example, the pictures of the marks E P , E K , and E N ) occurs in an original picture OF1, and the other original pictures OF1 that are not retained (for example, the picture of the unmarked event) are deleted. Among them, the above events are, for example, object movement, flame or smoke.

對於原始畫面OFa的存續時間落於時間區間TP2（對應第二時間區間）的第二原始畫面OF2（亦即標記EP 、EK 及EN 的畫面），保留在第二原始畫面OF2中對應的事件強度較高的原始畫面OF2並且刪除未保留的其他原始畫面OF2。舉例來說，在第二原始畫面OF2中包括對應一事件的多個一般畫面（例如標記EP 的畫面，可為行人走過的背影）、多個關鍵畫面（例如標記EK 的畫面，可為畫面中的車牌或人臉）及多個必要關鍵畫面（例如標記EN 的畫面，可為出現火焰事件其事件前後10秒的連續畫面），畫面處理電路140保留第二原始畫面OF2中對應的事件強度較高的關鍵畫面EK 及必要關鍵畫面EN ，且刪除其他第二原始畫面OF2，亦即刪除事件的一般畫面EP 。The second original picture OF2 (ie, the pictures marked with E P , E K and E N ) whose duration of the original picture OFa falls within the time interval TP2 (corresponding to the second time interval) remains in the second original picture OF2. The event intensity is higher for the original picture OF2 and the other original picture OF2 not retained is deleted. For example, the second original picture corresponding to a plurality of OF2 includes a general picture of events (e.g., labeled E P picture, pedestrians may walk back), a plurality of key picture (e.g., picture labeled E K, may For the license plate or face in the picture) and a plurality of necessary key pictures (for example, the picture marked E N may be a continuous picture of 10 seconds before and after the event in which the flame event occurs), the picture processing circuit 140 retains the corresponding in the second original picture OF2 The key picture E K with the higher event intensity and the necessary key picture E N , and the other second original picture OF2 are deleted, that is, the general picture E P of the event is deleted.

對於原始畫面OFa的存續時間落於時間區間TP3（對應第三時間區間）的多個第三原始畫面OF3（亦即標記EK 及EN 的畫面），畫面處理電路保留第三原始畫面OF3的必要關鍵畫面EN ，且刪除第三原始畫面OF3的關鍵畫面EK 。對於原始畫面OFa的存續時間落於時間區間TP4（對應第四時間區間）的多個第四原始畫面OF4（亦即標記EN 的畫面），畫面處理電路140刪除所有的第四原始畫面OF4。For a plurality of third original pictures OF3 (ie, pictures of the marks E K and E N ) whose duration of the original picture OFa falls within the time interval TP3 (corresponding to the third time interval), the picture processing circuit retains the third original picture OF3 The key picture E N is necessary, and the key picture E K of the third original picture OF3 is deleted. A fourth plurality of original picture OF4 to the survival time of the original picture OFa TP4 fall within a time interval (corresponding to the fourth time interval) (i.e. labeled E N picture), the picture processing circuit 140 to delete all of the fourth original picture OF4.

進一步來說，必要關鍵畫面的事件強度高於非必要關鍵畫面（亦即一般畫面及關鍵畫面）的事件強度。因此，畫面處理電路140會保留在第二原始畫面OF2中的所有必要關鍵畫面EN ，且可選擇性地保留在第二原始畫面OF2中的全部或部分的關鍵畫面EK ，但是一般畫面EP 則會全部刪除。Further, the event intensity of the necessary key pictures is higher than the event intensity of the non-essential key pictures (ie, the general picture and the key picture). Therefore, the picture processing circuit 140 retains all the necessary key pictures E N in the second original picture OF2, and can selectively retain all or part of the key pictures E K in the second original picture OF2, but the general picture E P will all be deleted.

在本發明的一實施例中，關鍵畫面EK ）的過濾可以採依時間進行，亦即設定關鍵畫面EK 的畫面率（Frame rate）；或者，可以比較關鍵畫面的事件強度，並且保留事件強度較高的關鍵畫面EK 。並且，關鍵畫面EK 的事件強度可正比於移動物件於對應第二原始畫面OF2中的比例。In an embodiment of the present invention, the filtering of the key picture E K ) may be performed according to time, that is, the frame rate of the key picture E K is set; or, the event intensity of the key picture may be compared, and the event is retained. The key picture E K with higher intensity. Moreover, the event intensity of the key picture E K can be proportional to the ratio of the moving object in the corresponding second original picture OF2.

在本發明的一實施例中，必要關鍵畫面EN 例如為包含移動物件的區隔特徵的第二原始畫面OF2，關鍵畫面EK 為包含移動物件但未包含區隔特徵的第二原始畫面OF2。其中，當移動物件為動物時，上述區隔特徵可以為動物或人的臉部；當移動物件為交通工具時，上述區隔特徵可以為交通工具的車牌，上述為舉例以說明，本發明實施例不以此為限。In an embodiment of the invention, the necessary key picture E N is, for example, a second original picture OF2 containing the segmentation feature of the moving object, and the key picture E K is a second original picture OF2 containing the moving object but not including the segmentation feature. . Wherein, when the moving object is an animal, the segmentation feature may be an animal or a person's face; when the moving object is a vehicle, the segmentation feature may be a vehicle license plate, which is illustrated by way of example and implemented by the present invention. The example is not limited to this.

依據上述，本案的監控資料的原始畫面儲存系統依據原始畫面OFa的事件強度，決定每張原始畫面OFa的保存時間，並且在原始畫面OFa不保留時於對應的時間區間內進行刪除。藉此，可節省監視畫面的儲存容量，並且保留了監視畫面於法律上的有效性。According to the above, the original picture storage system of the monitoring data of the present case determines the save time of each original picture OFa according to the event intensity of the original picture OFa, and deletes it in the corresponding time interval when the original picture OFa is not retained. Thereby, the storage capacity of the monitor screen can be saved, and the legal validity of the monitor screen is preserved.

圖3A至圖3C分別為依據本發明一實施例的原始畫面的判斷示意圖。請參照圖3A，在本實施例中，假設事件為有行人走過，並且事件中的原始畫面全部只拍到人的背影，亦即事件中的原始畫面都是一般畫面EP 。當事件中只存在一般畫面EP 時，事件的原始畫面無法保留到時間區間TP2，亦即事件的原始畫面的保留時間可能過短。此時，可將事件的原始畫面中選取其中一張以上的原始畫面作背影清楚的代表，並且將上述選取的原始畫面設定為關鍵畫面EK ，以使事件的原始畫面可保留到時間區間TP2。3A-3C are schematic diagrams of determining an original picture according to an embodiment of the invention. Referring to FIG. 3A, in the embodiment, it is assumed that the event is that a pedestrian has passed, and all the original pictures in the event only capture the back of the person, that is, the original picture in the event is the general picture E P . When only the general picture E P exists in the event, the original picture of the event cannot be retained to the time interval TP2, that is, the retention time of the original picture of the event may be too short. At this time, one or more original pictures of the original picture of the event may be selected as a representative of the back view, and the selected original picture is set as the key picture E K so that the original picture of the event can be retained to the time interval TP2 .

請參照圖3B，在本實施例中，假設事件為有行人走過，其中有人臉且人臉最清楚的原始畫面設定為必要關鍵畫面EN ，有人臉且可分辨特徵的原始畫面設定為關鍵畫面EK ，只拍到背影或拍到的人臉太小或模糊不清的原始畫面設定為一般畫面Ep。Referring to FIG. 3B, in the embodiment, it is assumed that the event is a pedestrian passing, and the original picture with the face and the face is set to the necessary key picture E N , and the original picture of the face and the distinguishable feature is set as the key. The picture E K is set to the normal picture Ep only when the back picture is taken or the face that is captured is too small or blurred.

請參照圖3C，在本實施例中，假設事件為有行人走過且發生特定事件（在此為爆炸事件），並且事件中的原始畫面全部只拍到人的背影，亦即事件中的原始畫面應該為一般畫面EP 。由於爆炸事件的發生，代表事件應該延長保留時間，此時會將事件的原始畫面中選取其中一張以上的原始畫面作背影清楚的代表，並且將上述選取的原始畫面設定為必要關鍵畫面EN ，而事件中的其他原始畫面仍設定為一般畫面EP 。Referring to FIG. 3C, in the embodiment, it is assumed that the event is that a pedestrian has passed and a specific event occurs (here, an explosion event), and all the original pictures in the event only capture the back of the person, that is, the original in the event. The picture should be the normal picture E P . Due to the occurrence of the explosion event, the representative event should be extended for the retention time. At this time, one or more original pictures in the original picture of the event are selected as the representative of the back view, and the original picture selected above is set as the necessary key picture E N . And the other original pictures in the event are still set to the normal picture E P .
